Description

Technical Field

[0001] This utility model relates to the technical field of toxic gas concentration detection and early warning equipment, and in particular to a portable toxic gas concentration detection and early warning equipment. Background Technology

[0002] Toxic gas detection and early warning devices can be used to monitor the concentration of toxic gases in the petroleum, chemical, and pharmaceutical industries in real time to ensure worker safety.

[0003] For example, utility model application number 201811037508.3 discloses a methane gas detection and hazardous concentration warning device. This device utilizes a combination of a display screen, an audible and visual alarm, buttons, a vent plate, a rotating shaft, a movable shaft, a rotating disk, a methane detector, a methane concentration sensor, and a rotating mechanism. The methane detector and methane concentration sensor effectively detect methane in the air. The methane concentration sensor transmits the detected data to a data comparator, which compares it to an alarm threshold. If the result is higher than the alarm threshold, it indicates that the methane concentration is too high. The data comparator then feeds the alarm threshold back to the central processing unit via a feedback module. The central processing unit controls the display screen to show the information and activates the audible and visual alarm. The display screen allows staff to promptly access methane concentration information, and the audible and visual alarm effectively prevents situations where staff are unaware of the methane concentration, thus improving the practicality and functionality of the detection equipment.

[0004] The above-mentioned applications still have shortcomings:

[0005] This type of methane gas detector and hazardous concentration early warning device has limited detection range for gases such as methane. A methane gas detector installed on one side can only monitor a portion of the surrounding gas, resulting in a very small monitoring range. Furthermore, it cannot detect and warn in confined spaces, such as pipelines, thus limiting its application.

[0006] To address this issue, a portable toxic gas concentration detection and early warning device was designed. Utility Model Content

[0007] The main purpose of this invention is to provide a portable toxic gas concentration detection and early warning device to solve the related technical problems mentioned in the background art.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] A portable toxic gas concentration detection and early warning device includes a detection and early warning instrument. A limiting tube is installed on the top of the detection and early warning instrument, and an air inlet pipe is installed on the top of the instrument and inside the limiting tube. A telescopic tube is fixed to one end of the air inlet pipe, and an adsorption head is installed at the end of the telescopic tube away from the detection and early warning instrument. Metal rings are evenly arranged on the outer side of the telescopic tube. A mounting plate is evenly arranged on one side of the detection and early warning instrument, and retaining rings are symmetrically installed on one side of the mounting plate. A protective tube is engaged inside the retaining rings, and magnetic rings are evenly arranged inside the protective tube, with the magnetic rings movably connected to the metal rings. A protective component is provided on the front of the detection and early warning instrument.

[0010] Preferably, the detection and early warning instrument has a limiting groove on one side, a limiting ring is provided inside the top of the limiting tube, and a fixing ring is provided at the end of the protective tube near the limiting tube.

[0011] Preferably, the front of the detection and early warning device is symmetrically provided with slide bars, and magnetic sheets two are fixed on the front of the detection and early warning device and at both ends of the slide bars. A protective plate is slidably installed on the outside of the slide bars, and magnetic sheets one matching the position of magnetic sheets two are evenly provided on the side of the protective plate close to the detection and early warning device.

[0012] Preferably, both the limiting ring and the fixing ring have anti-slip textures on their outer sides, and the limiting ring is a rubber ring.

[0013] Preferably, a strap is installed on the other side of the detection and early warning device, and the strap is an elastic band.

[0014] Preferably, all the retaining rings are semi-circular arc plates, and the inside of each retaining ring is provided with an anti-slip layer.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model provides a portable toxic gas concentration detection and early warning device. Through the combined use of a detection and early warning instrument, a limiting tube, an air inlet tube, a telescopic tube, a metal ring, a mounting plate, a retaining ring, a protective tube, a magnetic ring, and an adsorption head, it can detect and warn of toxic gas concentrations in spaces of different sizes. When not in use, the telescopic tube can be folded back into the protective tube, which not only reduces the footprint but also provides protection for the outside of the telescopic tube, thereby improving the practicality of the portable toxic gas concentration detection and early warning device.

[0017] By using the combination of the limiting groove, the limiting ring and the fixing ring, the protective tube is taken out from the retaining ring, and then the protective tube is flipped so that the end with the fixing ring is inserted into the inside of the limiting tube. The friction between the limiting ring and the fixing ring is used to splice and fix the protective tube and the limiting tube into one piece, so that different positions and angles of the detection space can be monitored, thereby improving the flexibility of the portable toxic gas concentration detection and early warning device.

[0018] By using the slider, protective plate, magnetic sheet one, and magnetic sheet two in combination, when not in use, the protective plate is pulled down until it completely covers the buttons and display screen on the detection and warning device. At the same time, magnetic sheet one on the protective plate is attracted to magnetic sheet two on the detection and warning device, thus protecting the display screen and buttons on the front of the detection and warning device and avoiding problems such as bumps or accidental touches. This improves the protective effect of the portable toxic gas concentration detection and warning device. Attached Figure Description

[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] Example 1

[0025] like Figures 1-3 As shown, this embodiment provides a portable toxic gas concentration detection and early warning device, including a detection and early warning instrument 1. A limiting tube 2 is installed on the top of the detection and early warning instrument 1. An air inlet pipe 3 is installed on the top of the detection and early warning instrument 1 and inside the limiting tube 2. A telescopic tube 4 is fixed to one end of the air inlet pipe 3. An adsorption head 10 is installed at the end of the telescopic tube 4 away from the detection and early warning instrument 1. Metal rings 5 ​​are evenly arranged on the outer side of the telescopic tube 4. A mounting plate 6 is evenly arranged on one side of the detection and early warning instrument 1. A retaining ring 7 is symmetrically installed on one side of the mounting plate 6. A protective tube 8 is engaged inside the retaining ring 7. Magnetic rings 9 are evenly arranged inside the protective tube 8 and are movably connected to the metal rings 5. A protective component 19 is provided on the front of the detection and early warning instrument 1. A limiting groove 11 is opened on one side of the detection and early warning instrument 1. A limiting ring 12 is provided inside the top of the limiting tube 2. A fixing ring 13 is provided at the end of the protective tube 8 near the limiting tube 2.

[0026] Pull the adsorption head 10 out to the bottom. The adsorption head 10 drives the top telescopic tube 4 and metal ring 5 to move and detach from the inside of the protective tube 8. Select the extension length of the telescopic tube 4 according to the depth of the detection position. After the detection is completed, retract the metal rings 5 ​​one by one and insert them into the inside of the protective tube 8. At the same time, the metal rings 5 ​​adhere to the inside of the magnetic ring 9. Store the telescopic tube 4 and metal ring 5. Take the protective tube 8 out of the retaining ring 7. Then flip the protective tube 8 so that the end with the fixing ring 13 is inserted into the inside of the limiting tube 2. Utilize the friction between the limiting ring 12 and the fixing ring 13 to splice and fix the protective tube 8 and the limiting tube 2 into one piece. This allows for monitoring of different orientations and angles of the detection space.

[0027] Example 2

[0028] In this embodiment, as Figures 1-3 As shown, the front of the detection and early warning device 1 is symmetrically provided with a slider 14. On the front of the detection and early warning device 1, magnetic pieces 17 are fixed at both ends of the slider 14. A protective plate 15 is slidably installed on the outside of the slider 14. On the side of the protective plate 15 near the detection and early warning device 1, magnetic pieces 16 are evenly provided, which match the positions of magnetic pieces 17.

[0029] When not in use, pull down the protective plate 15 until it completely covers the buttons and display screen on the detection and warning device 1. At the same time, the magnetic sheet 16 on the protective plate 15 will be attracted to the magnetic sheet 17 on the detection and warning device 1, thus completing the protection of the display screen and buttons on the front of the detection and warning device 1.

[0030] In this embodiment, both the outer sides of the limiting ring 12 and the fixing ring 13 are provided with anti-slip textures, and the limiting ring 12 is a rubber ring.

[0031] The anti-slip texture between the limiting ring 12 and the fixing ring 13 increases the friction between the protective tube 8 and the limiting tube 2, thereby improving the sturdiness after splicing.

[0032] In this embodiment, a strap 18 is installed on the other side of the detection and warning device 1, and the strap 18 is an elastic band.

[0033] The elastic strap 18 can be used to secure it to the wrist, and the elastic material allows for a wider range of fixation.

[0034] In this embodiment, all retaining rings 7 are semi-circular arc plates, and all retaining rings 7 have an anti-slip layer inside.

[0035] The semi-circular retaining ring 7 can better engage with the outside of the protective tube 8, and the anti-slip layer increases the firmness.

[0036] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
